A zombie process is a process that was started by a parent process in such a way that it is expected that the child process will exit and the parent will acknowledge the exit; but the parent never did. You used to see this all the time on a Unix box in the past. Now days, the "init" process usually becomes the foster parent so you don't have zombies piling up as time goes on. There was never anything terribly wrong with zombies (as long as it wasn't some ridiculous amount) since the only resource they tied up (at least in theory) was a process ID number; and it made for a messy, disconcerting ps output. I know absolutely nothing about Sun clustering; but I am wondering if you are having trouble with network file system reads and writes. NFS problems can cause hanging. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephen Lee INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
